Pump Description
Basic Pump
Pump Controls Types
Figure 1 shows the basic construction of the PVM series
piston pump. Major parts include the 1. Shaft 2. Housing,
3. Swash plate,4. Rotating group, 5. Valve plate, 6. Control
sleeve, 7. Control rod, 8. End Cover, 9. Control 10. Flange
Three common pump control types are available. One type is
the standard “A” compensator control that limits pump outlet
pressure to a desired level. The other type is the “B+C”
pressure limited/load sensing control. Now available is the
“IC” (Industrial Control) which can be used as a load sensing
compensator, remote compensator control and electrohydraulic control. These limit pump outlet pressure and also regulate
pump displacement to match load requirements. A cold start
valve option is also available.
Figure 1
Pump Operation
In axial piston pumps, the pistons reciprocate parallel to the
axis of rotation of the cylinder barrel. The simplest type of
axial piston pump is the swash plate in-line design. The cylinder barrel in this pump is turned by the drive shaft. Pistons
fitted to bores in the cylinder barrel are connected through
piston shoes and a shoe plate, so that the shoes bear against
an angled swash plate.
As the barrel turns, the piston shoes follow the swash plate,
causing the pistons to reciprocate. The ports are arranged in
the valve plate so that the pistons pass the inlet as they are
pulled out and pass the outlet as they are forced back in. The
displacement of axial piston pumps is determined by the size
and number of pistons, as well as the stroke length which
is determined by the angle of the swash plate. In variable
displacement Models of the in-line pump, the swash plate is
installed in a saddle Bearing. “Pivoting” the swash plate in
saddle bearings changes the swash plate angle to increase or
decrease the piston stroke.

Inspection, Repair & Part
Replacement
Inspection
Before inspection of parts, clean with a solvent that is compatible with system fluid.
Rotating Group Parts
1. Inspect cylinder block face for wear, scratches, and/or
erosion. If cylinder block condition is questionable, replace
the entire rotating group.
2. Remove the pistons, shoe retainer, and pivot from piston
block. The piston block assembly doesn’t need to be
disassembled unless the internal pins or spring are
damaged.
3. Check each cylinder block bore for excessive wear. Use
the piston and shoe S/A (37) for this purpose. The pistons
should be a very close fit and slide in and out of the
cylinder block bores. NO BINDING CAN BE TOLERATED.
If binding occurs, clean the cylinder block and pistons.
Lubricate the cylinder block bores with clean fluid and try
again. Even minor contamination of the fluid may cause a
piston to freeze up in a cylinder bore.
Note: Do not lap the face of piston block assembly
4. Inspect each of the nine piston and shoe subassemblies
(31) for a maximum end play of 0.005 inch between the
piston and shoe. Also check the face dimension of each
shoe. The face dimension must be within 0.001 inch.
5. Inspect shoe retainer and pivot for wear and/or scratches.
If condition is questionable, replace entire rotating group.
Piston S/A Tolerances
This dimension must be Maintained on all nine shoes within
0.001 inch.
Shoe face rides on swash plate. Shoe must swivel smoothly
on ball. End play must not exceed 0.005 inch.

Inspection, Repair & Part
Replacement
End Cover & Associated Parts
1. Inspect end cover for erosion, cracks and burrs. Clean up
minor burrs with an India Stone. If erosion or cracks are found
replace the end cover.
2. Inspect roller bearing and bearing race for nicks and pitting.
Make sure the roller bearing turns freely within the bearing
race. If the roller bearing needs replacement, both the roller
bearing and the bearing race must be replaced.
3. Inspect valve plate for erosion, excessive wear, heavy
scratches and cracks. If any of the above conditions are
found, replace the valve plate.
system should be drained and the reservoir cleaned before
new fluid is added.
3. Filter elements also should be checked and replaced
periodically. A clogged filter element results in a higher pressure drop. This can force particles through the filter which
would ordinarily be trapped, or can cause the by-pass to open,
resulting in a partial or complete loss of filtration.
4. Air bubbles in the reservoir can ruin the pump and other
components. If bubbles are seen, locate the source of the air
and seal the lead.
4. Inspect control piston and maximum displacement screw
for burrs, scratches and cracks. Clean up minor scratches
with 500 grit paper. Remove burrs with an India stone. The
control piston should move freely in the bore.
Swash plate Parts
1. Inspect swash plate face for wear, roughness or scoring.
Check the swash plate hubs and bearing surfaces for wear
and cracks. Replace if defective.
2. Inspect saddle bearing surfaces for wear, pitting, and
smooth operation. Replace if necessary.
Shaft/Housing Parts
1. Inspect drive shaft for wear, stripped splines, and burrs.
Remove burrs with an India stone. Inspect the contact area of
bearing and shaft seal. Replace the drive shaft if wear or scoring is greater than 0.005 T.I.R. (total indicator reading).
2. Inspect drive shaft bearing for roughness, pitting of rollers
and excessive end play. Replace, if defective. If the bearing
needs to be replaced, the bearing race also requires replacement
3. Inspect housing mounting flange for nicks and burrs. Remove minor nicks and burrs with an India stone. Also check
the housing for damaged or stripped threads. If any thread is
damaged, replace the housing.
4. Check remaining pump parts for excessive wear, damaged
threads, burrs, cracks and erosion. Replace any part that is in
questionable condition.
The following should be checked regularly:
1. All hydraulic connections must be kept tight. A loose connection in a pressure line will permit the fluid to leak out. If
the fluid level becomes so low as to uncover the inlet pipe
opening in the reservoir, extensive damage to the pump can
result. In suction or return lines, loose connections permit air
to be drawn into the system resulting in noisy and/or erratic
operation.
2. Clean fluid is the best insurance for long service life. Therefore, the reservoir should be checked periodically for dirt or
other contaminants. If the fluid becomes contaminated, the

Assembly
Assembly must be conducted in a clean environment.
Dispose of leakage oil and oily cloths in an environmentally
responsible manner. Before assembly process can begin, all
parts have to be initially demagnetized and carefully clean
all parts and blow out holes with compressed air. Tighten all
screws plugs to the specified torque (see Appendix). Exceptions are specified in the text. Lubricate O-rings and shaft
sealing rings lightly with acid free lubricant for easier installation and to hold the O-ring in place in its groove or cavity.
3. The Control Sleeve and Piston Sub-assembly to the
Swash Plate
For fixed hold down assemblies (57cc to 141cc):
1. Assembly of the Rotating Group
2. Control Sleeve and Control Piston
•
Place the swash plate with the control piston/sleeve
attached face down on the rotating group shoe faces.
Invert the swash plate and rotating group, install the
spacers, spacer limiter plates (bronze side towards the
spacers) and retaining screws.
Note: Torque the retaining screws to the specified torque
For Spherical Hold down Assemblies (18cc and 45cc):
•
Install the pin into the seat with the pin partially coming out
of the flat part of the seat. Set the flat side of the seat
against the swash plate and press the pin through the seat
into the swash plate.
Note: Extreme care should be taken when installing the major and minor
diameter O-rings and backup-rings. The minor OD seals are installed in
reverse order to the major OD seals.
Note: The pin should be pressed flush or slightly below flush the surface of
the seat. A roll pin punch or a pin setter can be used to properly position the
pin into the spherical seat.

Testing
Start–up Procedure
Troubleshooting
Make sure the reservoir and circuit are clean and free of dirt/
debris prior to filling with hydraulic fluid. Fill the reservoir with
filtered oil to a level sufficient to prevent vortexing at suction connection to pump inlet. It is good practice to clean the
system by flushing and filtering using an external slave pump.
Before starting the pump, fill with fluid through one of the
ports. This is particularly important if the pump is above the
fluid level of the reservoir. When initially starting the pump,
remove all trapped air from the system. This can be accomplished by loosening the pump outlet fittings or connections
before starting the pump or by using an air bleed valve. All
inlet connections must be tight to prevent air leaks. Once the
pump is started it should prime within a few seconds. If the
pump does not prime, check to make sure that there are no
restrictions between the reservoir and the inlet to the pump,
and there are no air leaks in the inlet line and connections.
Also check to make sure that trapped air can escape at the
pump outlet. After the pump is primed, tighten the loose
outlet connections, and then operate for five to ten minutes
(unloaded) to remove all trapped air from the circuit. If reservoir has a sight gauge, make sure the fluid is clear – not milky.
Add fluid to the reservoir up to the proper fill level. Perform
functional test on pump according to Eaton test procedure.
Contact your area sales manager for more information.
The troubleshooting chart below lists common difficulties
experienced with pumps and hydraulic systems. The chart
indicates probable causes and remedies for each of the
troubles listed.
Trouble
Probable Cause
Remedy
Excessive noise in pump
low oil level in reservoir
fill reservoir to pepper level with recommended fluid. DO NOT overfill or
damage may result.
1. Open reservoir cap and operate hydraulic system until purged.
Air in the system
2. “Bleed“ hydraulic lines at point downstream of the pump while the
system is under pressure.
Vacuum condition
Check inlet (suction) lines and fittings for leaks.
Oil tool thick
Be certain correct type of oil is for refilling or adding to the system.
Cold weather
Run hydraulic system until unite is warm to the touch and noise disappears.
Hydraulic pump over heating
Internal leakage
If established that excessive internal leakage exist within the pump, return to
maintenance shop for evaluation and repair.
Heat exchanger not functioning
Locate trouble and repair or replace.
Fluid level low
Add oil to proper operating level.
System not developing pressure
Compensator malfunction
Replace or repair.
Loss of fluid internally (slippage)
Return to maintenance shop for evaluation and repair.
Loss of fluid
Ruptured hydraulic line
1. Check all external connections, tubing and hoses.
2. Tighten connections, replace ruptured tube or hose.
Observe mating section of pump for leaks. Replace seals of gaskets in
possible. Check all system components for leaks.
Leaking gaskets or seals in the
system
Miscellaneous
Broken or mis-adjusted
pump control
Disconnected or broken drive
